Emacs regular expressions forked from everyone else long ago.
This makes it official and should allow simplification later.
etags.c now uses the glibc regex API, falling back on a
Gnulib-supplied substitute lib/regex.c if necessary.
Emacs proper now uses its own regular expression module.
Although this patch may look dauntingly large, most of it
was generated automatically by admin/merge-gnulib
and contains an exact copy of the glibc regex source,
and the by-hand changes do not grow the Emacs source code.
* admin/merge-gnulib (GNULIB_MODULES): Add regex.
(AVOIDED_MODULES): Add btowc, langinfo, lock, mbrtowc, mbsinit,
nl_langinfo, wchar, wcrtomb, wctype-h.
* lib-src/Makefile.in (regex-emacs.o): Remove; Gnulib does it now.
(etags_deps, etags_libs): Remove regex-emacs.o.
* lib-src/etags.c: Go back to including regex.h.
(add_regex): Use unsigned char translation array,
since glibc regex requires that.
* lib/Makefile.in (not_emacs_OBJECTS, for_emacs_OBJECTS): New macros.
(libegnu_a_OBJECTS): Use them, to avoid building e-regex.o.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/regcomp.c, lib/regex.c, lib/regex.h, lib/regex_internal.c:
* lib/regex_internal.h, lib/regexec.c, m4/builtin-expect.m4:
* m4/eealloc.m4, m4/glibc21.m4, m4/mbstate_t.m4, m4/regex.m4:
New files, copied from Gnulib.
* src/regex-emacs.h, src/conf_post.h:
(RE_TRANSLATE_TYPE, RE_TRANSLATE, RE_TRANSLATE_P):
Move from src/conf_post.h to src/regex-emacs.h,
so that they don’t interfere with compiling lib/regex.c.
This is in preparation for using Gnulib regex for etags,
to avoid collisions in include directives.
* src/regex-emacs.c: Rename from src/regex.c.
* src/regex-emacs.h: Rename from src/regex.h. All uses changed.
* test/src/regex-emacs-tests.el: Rename from test/src/regex-tests.el.

(debugger-insert-backtrace): Remove.

(debugger--insert-header): New function.
(debugger-continue, debugger-return-value): Change check for flags to

* src/xdisp.c (redisplay_window): Make sure desired_matrix is
cleared before calling try_window. This is important when
display-line-numbers is non-nil, because line-number display code
assumes each glyph row is completely cleared when it is called to
produce a line number. (Bug#32358)
* src/textprop.c (set_text_properties): If the call to
modify_text_properties modifies the interval tree as side effect,
recalculate the correct interval for START and END. (Bug#32265)
Similarly as `create-directory', `dired-create-directory',
the new commands create the parent dirs as needed (Bug#24150).

can be used in #if.
* src/lread.c, src/print.c: Include <ieee754.h> if
IEEE_FLOATING_POINT, not if HAVE_IEEE754_H.
* src/lread.c (string_to_number):
* src/print.c (float_to_string):
Process NaNs only on IEEE hosts, and assume <ieee754.h>
in that case.
Add an Edebug matching function for cl-macrolet which keeps track of
its bindings and treats them as macros without Edebug specs when found
in the body of the expression.
* lisp/emacs-lisp/edebug.el (edebug--cl-macrolet-defs): New variable.
(edebug-list-form-args): Use it.

* test/lisp/emacs-lisp/edebug-resources/edebug-test-code.el
(edebug-test-code-use-cl-macrolet): New function.
The done items separator is not reachable by todo-mode navigation
commands, but it is e.g. by C-n and C-p. Ensure that invoking
todo-mode commands with point on the separator does not result in
unexpected results, errors or file corruption (bug#32343).
* lisp/calendar/todo-mode.el (todo-insert-item--basic): Make
copying item and inserting item "here" noops when invoked on done
items separator. Consolidate error handling of these cases. Also
restrict "here" insertion to valid positions in the current
category, since this is simpler than the previous behavior of
inserting as the first item, which was moreover undocumented,
counterintuitive and superfluous.
(todo-set-item-priority, todo-move-item, todo-item-done)
(todo-item-start, todo-item-end): Make noops when invoked on done
items separator.
* test/lisp/calendar/todo-mode-tests.el: Require ert-x.

(todo-test-done-items-separator07): New tests.
These should be portable nowadays.
* src/data.c (isnan): Remove.
* src/floatfns.c (isfinite, isnan): Remove.
* src/print.c: Include math.h, for isinf and isnan.
(float_to_string): Simplify by using them.
